Producer-director David Monaghan has been researching the possible connection since he attended Rogers' 1997 murder trial in Tampa. The former Hamilton, Ohio, taxi driver is serving two death sentences for two 1995 murders - the stabbing of Tina Cribbs in a Tampa motel and the strangulation of Sandra Gallagher of Van Nuys, Calif.

Glen Rogers made headlines nationwide when he was captured on Nov. 13, 1995 - driving Cribbs' car a week after her murder - after a 15-mile high-speed chase by Kentucky State Police near Richmond, Ky.

At the time of his arrest, Rogers claimed he had killed 70 victims. Filmmaker Monaghan says he was "very skeptical" about the Simpson claim until he heard that Rogers, while working as a painter in Los Angeles, had told his brother Clay and sister Sue Rogers of Hamilton in early 1994 that he had met Nicole Brown Simpson.

Former Cincinnati Enquirer reporter John Eckberg, who co-wrote a book called Road Dog about Glen Rogers in 2003, says he did long-distance research about Rogers' Simpson-Goldman allegations but couldn't nail it down.

"We suspected it. I firmly believe he probably was involved in some way, shape or form," Eckberg says.

Narcotics officers often paid Glen Rogers as a drug informant to set up buys, Kilgour says.

Clay Rogers' relationship with his brother changed after Clay Rogers found the body of Glen Rogers's roommate - Mark Peters, 72, a retired electrician - wrapped in a curtain in the Rogers family cabin near Beattyville, Ky. Clay Rogers, who had heard his brother boast several times that he had killed 50 people, led Hamilton police to the body.

"I came to the realization I wasn't turning in my brother. I was turning in a serial killer," Clay Rogers says in the film.

Glen Rogers was never charged with Peters' murder. He was also a suspect in - but never charged - with two other brutal stabbing deaths in fall 1995 while en route from California to Tampa:

â?¢ Price, 34, in Jackson, Miss.

â?¢ Andy Jiles Sutton, 37, in Bossier City, La.

And there could be many more, Monaghan told The Enquirer. Glen Rogers indicated "three innocent men are on death row for killings he committed," Monaghan says.

"It's my hope that authorities in California, Ohio and Kentucky would re-open the Glen Rogers case and look again at the number of victims Glen Rogers may have claimed. I'd be happy to cooperate," Monaghan says.

"Glen Rogers' claim of having killed 70 people is believable. He was literally able to get away with murder for years," Monaghan says.
